With reference to the news published on 07 December, we are pleased to inform users of the successful dissemination of the Copernicus Sentinel-2 Level-2A products worldwide on the data hubs as of 13 December, starting from Sentinel-2B sensing orbit 9243 and Sentinel-2A sensing orbit 18152.

Due to the transition to Level-2A global distribution, the availability of Level-2A products on 12 December sensing over Europe was delayed and completed on 14 December.

Following successful completion of the Copernicus Sentinel-3B Commissioning Phase, the Level 1 (OL_1_EFR and OL_1_ERR) both Near-Real-Time (NRT) and Non-Time-Critical (NTC) production of the Ocean and Land Colour Instrument (OLCI) instrument will be published on the Collaborative Data Hub starting from 17 December 2018.

The Product Notices related to the current release are available to download:

Copernicus Sentinel-1A was unavailable from 9 December 2018 18:53 UTC to 10 December 2018 08:57 UTC, due to a SAR anomaly.

No data were generated during this period.

We apologize for any inconvenience caused.

Maintenance on ColHub Node 1 on Thursday, 22 November 2018

19 Nov 2018

Collaborative users are informed that on Thursday, 22 November 2018 a maintenance activity will be performed on Access Node 1.
The maintenance will start at 8:00 UTC and will end at 12:00 UTC.
During the maintenance activity two short service interruptions will occur and the publication of new products will be temporarily suspended.
We apologize for the inconvenience that this might cause to your activities.

New Copernicus Sentinel-2 Level-2A Processing Baseline

16 Nov 2018

On 21 November 2018, a new Processing Baseline (02.11) will be deployed for Copernicus Sentinel-2 Level-2A products.

This new Processing Baseline features a sole change, which consists in the improvement of the terrain correction algorithm in mountainous areas, in order to avoid artefacts for pixels under semi-transparent clouds.

S-3A OLCI publication on ColHub Node2 and ColHub Node 3 will be started with products ingested on 1st November 2018 at 00:00:00 UTC.

Temporary publication delay of Sentinel-2 products in the Data Hubs

05 Nov 2018

As a consequence of different contingencies at ground segment level, the availability in the Data Hubs of several Sentinel-2 products with sensing time between 30 October morning and 02 November morning is delayed.

The recovery of the missing products is ongoing and expected to be completed by next week.

We apologise for any inconvenience this may cause.

Infrastructure maintenance activity on 5 and 6 November 2018

31 Oct 2018

An unavoidable maintenance activity on the core infrastructure hosting the data hub service, involving replacement of switches interconnecting the servers to the rolling archive storage, is scheduled from 13:30 UTC on Monday 5 November to 11:00 UTC on 6 November 2018.

During the whole duration of the maintenance the following Data Hub Services will not be accessible:

The publication of Copernicus Sentinel-5P products on the respective Pre-operations Data Hub will not be affected by the maintenance.
The Collaborative Data Hub - Node 2 and Node 3 will continue to be accessible to their registered users, however the publications of the NTC products will be suspended for the whole duration of the maintenance window. The Sentinel-1 NRT products will continue to be published on the Collaborative Data Hub Node 2.

A temporary access hub will be activated for providing access to the last two weeks of Sentinel Data without registration. The temporary data hub will be available at the following address:https://tmphub.copernicus.eu/dhus

Copernicus Sentinel-2B MSI decontamination between 12 and 13 November 2018

30 Oct 2018

A routine decontamination activity of the Copernicus Sentinel-2B MSI is planned to take place over a continuous period of 24-hours between 12:00 UTC on 12 November and 12:00 on 13 November (corresponding approximately to the period between absolute orbits 8801 to 8815).
During this temporal window no MSI acquisition will take place.

Correlated calibration activities will be performed around the decontamination period that will further affect the nominal acquisition plan from 17:30 UTC on 11 November to 08:00 on 14 November.

Update of Sentinel-2 Level-1C and Level-2A Processing Baselines

29 Oct 2018

ESA is pleased to inform users of the forthcoming update of Copernicus Sentinel-2 L1C and L2A products featuring an improved data quality thanks to the following evolutions:

1. The crenellation effect at the edge of Sentinel-2 images will be significantly reduced by estimating the inverse locations for grid points lying just after the edge of the acquisition.
2. The accuracy of the tile sensing time reported in the tile metadata will be improved, by computing for each tile the average acquisition time of all relevant pixels. The new tile sensing time will be reported in the field General_Info/SENSING_TIME of the Tile Metadata without format change.
3. The detector footprint vector files will provide the precise location of the boundary between detectors, without overlap. Such improvement will allow the users to have an accurate estimation of the viewing direction for each pixel.
4. The correlated across-track noise currently visible on very dark images will be significantly reduced thanks to an improved radiometric correction algorithm.

The Sentinel-2 products featuring this update will start being disseminated on 06 November 2018, and will tag the new Processing Baselines 02.07 for L1C products and 02.10 for L2A products.

It is highlighted that the format of the L1C and L2A products generated with the new Processing Baselines remains compliant with the current version of the Product Specification Document (PSD v14.5), while an updated description of the new Tile Sensing time field of the Tile Metadata will be included as part of the next issue of the Product Specification Document.

Please note that the SNAP software is aligned to the new Processing Baselines as well.
